--- Comment #7 from Martin Jambor <jamborm at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #6) > Not so easily, the problem is that copy_forbidden is called without fun > being actually cfun, and set_cfun is very expensive. I think we can do the test without setting cfun by something similar to ipa_func_spec_opts_forbid_analysis_p in ipa-prop.c. > Do we ever call > copy_forbidden on functions that haven't been rewritten into SSA form yet? > If yes, it could be even set e.g. during gimplification (if (!optimize)). No, I don't think so. It's really a matter of cleanness and a fairly minor point at that.
